HOTBED-SASH.

T o all whom it may conce-rn.'

Be it known that I, DWIGHT Vt'msoN BEN- Nnrr. a citizen of the United States. resid.- ing at Somerton. in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hotbed-Sash; and I do declare the following to be a full, clear. and exact description of the invention, such as will enable others skilled in the art. to which it appertains to make and use the same.

This invention relates to improvements in glass roofs or hot bed sash.

The main object. of the invention is to provide means for securing the panes of glass in such a manner that substantially no shadows will be thrown by said securing means.

Another object is to provide simple and efficient glass securing means so constructed that a broken pane may be removed and replaced very quickly, thereby enabling a high temperature to be maintained under the sash with the outside temperature at a low point.

Another object is to provide a hot bed sash with cushioning means for the glass which will permit` the sash to be subjected to rough usage without danger of breakage.

lilith these and other objects in view the invention comprises certain novel constructions. combinations and arrangements of parts, as will be hereinafter more `fully described and claimed.

In the accompanying drawings Figure 1 represents a plan view of a section of hot bed sash constructed in accordance with this invention. Fig. Q is an enlarged transverse section thereof taken on line 2 2 of Fig. 1. F ig. 3 is an enlarged detail sectional view taken on a plane at right angles to Fig. 2 and on 3 3 of Fig. 2; Fig. 4 is a perspective view of one member of the clamp; Fig. 5 is a similar view of the other member.

In the embodiment illustrated, a sash frame l is shown of the usual rectangular construction with a plurality of panes of glass 2 mounted therein, with their edges abutting and with the strips of glass 3 arranged directly beneath the joints. These joints after being so arranged are treated to a solution of silicate of soda which renders them impervious to air and water.

The sash is preferably equipped with a double set of panes spaced apart to form an air space 4 between them. The frame 1 is Specification of Letters Patent.

rabbetcd on its upper and lower faces at its inner edge as shown at and (l to receive the glass. said recesses or rabbets being of a sufficient depth to receive the panes with their outer faces arranged flush with the upper and lower faces of the frame. lVooden fastening strips 9 are secured to the bars of the sash frame over the glass arranged in the rabbets thereof by screws 1U. These strips 9 are provided in their lower faces at their edges with channels 11 for the reception of cushioning` strips 1Q which forni a practically air and watertight connection between the strips and the glass and also reduce the danger of breakage upon rough handling.

Clamping members.y 13 and 1l, such as are shown in Figs. l and 5 are arranged on the outer faces of the fastening strips E) beneath the heads of the screws l() and serve to-rcliably hold the parts in operative position and may be quickly assemliiled and disassembled when desired. The lower member or block 13 is provided with a longitudinally extending key-hole slot 15 through which the screw l() is passed.y the lower end of said slot being countersunk as shown in Fig. 2 to provide for the yielding of said member when the wedge-like member la is forced into operative position. The outer face of the member 13 is inclined as shown in Fig. il and the wedge-Shaped member It which is also slotted longitudinally engaged with the shank of the screw 10 and is provided at its outer thicker end with an upturned lug 16 which is designed to receive the blow of a light tool for tightening or loosening said member 1l. Then it is desired to remove a pane for any purpose. the screws l() need not be loosened and a light blow is struck the lugs of the wedge members of the clamps which will loosen the clamp and permit the blocks 13 to be moved relatively to the screws 10 to bring the enlarged rounded portions of the key-hole slots therein opposite the screw heads; then the clamps may be removed and the fastening strip 9 disengaged from the pane permitting it to be quickly removed and another submitted. After the new pane has been placed in position the members of the clamp are replaced upon each other to cause them to firmly grip the fastening strip to which they are applied and securely engage it with the glass. As a substitute for the central supporting bar usually used, I employ a light truss 17 which Sti'tTQnS tho Saah and provides two indu@ or more sunlight for ovory `sash with prattirally nu shadow tilvrvfroni.
